THOMAS MIDGLEY, OF COLUMBUS, OHIO, ASSIGNOR TO THE MIDGLEY MANUFACTURING COMPANY, OF COLUMBUS, OHIO, A CORPORATION- OF OHIO.

METALLIC VEHICLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 7 72,812, dated. October 18, 1904.

Application filed August 21,1903. Renewed April 13, 1904:. Serial No. 203.034. (N0 model.)

To all whom it may cwwcrn:

Be it known that I, THoMAs MIDGLEY, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Metallic Vehicle -Wheels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such'as will enable others skilled in the art to which it- In the accompanying drawings, which form part of this specification, Figure 1 represents a transverse section of the rim of a wheel with a thimble secured. thereto. Fig. 2 is a plan view of a blank for a thimble; and Fig. 3, a longitudinal section of part of a rim of a wheel, a spoke, and a thimble in position in the outer end of the spoke.

, Reference being had to the drawings and the designating characters thereon. 1 indicates the rim of a wheel having a flat bearing or seat 2 for a tire (not shown) and a spoke-chain her 3, in which are tubular thimbles 4, only. one of which is shown, attached to the inner side of the seat 2 by a rivet 5 to hold the' thimble in position while a wheel is being as'-- sembled preparatory to brazing the parts to--- gether. g

6 indicates atubulanmetallic spoke whose outer end surrounds the thimble i in the spokechamber 3 and whose outer end extends to and abuts against the inner side of the seat 2, forming along annular bearing 7 between the outside of the body of the thimble and I the inside of the spoke and an annular bearing 8 between the spoke and the rim and the annular-end bearing 9 betweentlie spoke and the rim and Which bearing-surfaces of the several parts are metallically joined by dipping or immersing the wheel in a bath of molten brazing metal, which joins the outer flat end 10 of the thimble I to the rim of the wheel. The spoke thus secured resists all jars to which the wheel is subjected in use and makes the connection between the spoke and the rim of the wheel strong and durable.

The blank 11, from which the thimble is made, is out out of sheet-steel and bent into form-by suitable dies. 1

Having thus fully described my invention,

what I claim is- 1. A metallic vehicle-wheel rim, a tubular metallic spoke, and a metallic thimble at the outer end of the spoke and metallically joined thereto and to the rim.

' 2. A' metallic vehicle-wheel rim, a tubular metallic spoke, and a metallic thimble metallically joined thereto and to the inner side of the tire-seat of the rim.

THOMAS MIDGLEY.
